So I kept running out of space, so bought a 128gb USB drive (actually the size of the wifi adapter for the pi) and mounted it as /mnt/usbdrive, modified the fstab, and it all works nicely. Then I edited the config.yaml with the folders as so: Code: folder: timelapse: /mnt/usbdrive/timelapse timelapse_tmp: /mnt/usbdrive/timelapse_tmp This all works perfectly, it stores the JPGs in timelapse_tmp and creates a mpg file in time-lapse. So I can make actually higher quality movies as the JPGs are high quality and I can download them to my mac and combine them into a quicktime movie, but the issue is the time-lapse files are all blank. Permissions isn't it (see ls -l below). Code: pi@bigbox:/mnt/usbdrive $ ls -l total 100 drwx------ 2 root root 16384 Apr 11 22:57 lost+found drwxrwxrwx 2 pi root 4096 Apr 16 06:22 timelapse drwxrwxrwx 2 root root 81920 Apr 16 15:31 timelapse_tmp Any ideas for you octoprint whizzes?
